There is a Cisco Catalyst 6513 in my office. Recently we decided to setup redundant Supervisor Engine 720-3B. When we did it, its became STANDBY COLD, and then it reloads. IOS is equal on both supervisors. It must be STANDBY HOT (SSO) redundancy. Any ideas about it? There is a configuration and show ver and show module outputs, and log of my actions.
Thanks for help!

Please follow below document to deploy SSO mode on your Sups.
Also, looking at the version of code you are running, it is pretty old. You may want to upgrade to a newer version i.e SXI2a or SXI4a and test again.
